This is a Golite Ion, the shoulder strap has started cutting through right where it attaches to the pack near the hip belt. The cut in the strap looks to be about an 1/8 inch and has begun fraying. How would you fix this?

Great advice, I'll melt it a bit to prevent further fraying, then just let it be and keep an eye on it. I hang my bottle on there sometimes and the biner had a bit of a burr which cut into the webbing. It's been remedied. Thanks everybody!
